Hazard Warning Flashers
The hazard warning ashers warn others.
They also let police know you have a problem.
Your front and rear turn signal lamps will ash
on and off.
The hazard warning
asher button is
located on top of the
steering column.
The hazard warning ashers work no matter what
ignition position the key is in, and even if the
key is not in the ignition.
Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
When the hazard warning ashers are on, your

behind your vehicle.
Horn
To sound the horn, press the horn symbols
located on the steering wheel.

EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 279.
Battery Run-Down Protection
This feature shuts off the dome and reading
lamps, if they are left on for more than 10 minutes
when the ignition is turned off. The cargo lamp
will shut off after 20 minutes. This will keep
the battery from running down.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help you
park while in Reverse (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The URPA
system detects objects that are close to the rear of
the vehicle which are at least 10 inches (25.4 cm)
off the ground and below hood or trunk level. The
system detects objects up to 8 feet (2.5 m) behind
your vehicle. The URPA sensors determine how
close these objects are from your bumper within
this area.
228

For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 279.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
The vehicle may have two accessory power outlets
located below the climate control system, or may
have one accessory power outlet and one cigarette
lighter. The cigarette lighter is designed to t only in
the receptacle closest to the driver. There may be
another accessory power outlet in the rear cargo
area. If the vehicle has a oor console, there is an
outlet inside the storage bin and one on the rear of
the oor console.To use an outlet, remove the protective cap.
When not in use, always cover the outlet with the
protective cap. The accessory power outlet is
operational at all times.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
Certain power accessory plugs may not be
compatible to the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer
for additional information on the accessory
power plugs.
